    Phoronix: Intel Working On Implementing GuC Firmware Based Power Management For Linux

    Going back to 2017 was work on firmware-based power management for Intel graphics with its GuC implementation. That work didn't advance with the time but now with Intel renewing their work around GuC and with future hardware may mandate this binary-only firmware, they are again revisiting the GuC power management...

    Too bad they aren't planning this for older whiskey lake systems. Since the CVE related "Soft RC6" workaround my laptop draws ~30% more power during video playback or lightweight gaming.

      I can't find anywhere in the article or it's links what 'GuC' stands for?

          came to the comments both to find out what guc means and to express how dumb it is that i had to do so

            If that's the case then....

            With the GuC microcontroller being in better
            ....we have ourselves an ATM Machine folks.

            Edit: or is it technically an ATM Teller Machine?

                This is what happens when Michael is too lazy to look up the meaning of these short-form expressions himself.

                  Speaking of that, Slashdot still flatten UTF-8 punctuation into ASCII gibberish today. It is a mystery what took them forever to not fix it. UTF-8 has been standardized over 20 years.

                    I don't really know why that would be relevant for how Intel names things, but luckily for slashdot, μ is in the 8-bit extended ASCII character set.
